Oct 13, 2020 Coke Coke is a high-carbon product obtained by the destructive distillation of coal. The amount of carbon content in coke is so high that it is said to be an almost pure form of carbon. Coke is greyish-black in colour and is a hard, porous solid. Uses of Coke The most common use of coke is as a fuel for stoves, furnaces and blacksmithing.
